What is calendar september 1752?

September 1752 is a notable month in history due to the British Empire adopting the Gregorian calendar. As a result, 11 days were skipped. Specifically, September 3, 1752, was followed immediately by September 14, 1752. This change was implemented to align the British calendar with the rest of Europe. The calendar change affected not only Britain but also its colonies, including what would become the United States. The decision also had ramifications for setting tax dates and other legally defined periods.
